My Zoom API JWT Key leaked! What should I do?

What is a Zoom API JWT Key and how it is used?

A Zoom API JWT Key is a unique identifier used for authentication and authorization when accessing the Zoom API. It is a JSON Web Token (JWT) that contains information such as the issuer, expiration time, and access permissions.

When using the Zoom API JWT Key, developers typically use it for the following main use cases:

  • Authenticating and authorizing API requests: Developers use the JWT Key to securely authenticate their application with the Zoom API, allowing them to make authorized requests and access specific resources.
  • Generating access tokens: The JWT Key is used to generate access tokens that can be used by the application to interact with Zoom's API on behalf of the user, enabling functionalities such as creating meetings, managing users, and retrieving data.
  • Implementing secure communication: The JWT Key helps in establishing a secure communication channel between the application and the Zoom API, ensuring that sensitive data and information exchanged during API interactions are protected from unauthorized access.

1. Code snippets to prevent Zoom API JWT Key hardcoding using environment variables

Using environment variables for storing sensitive information such as Zoom API JWT Key in your code is a secure practice because:

  • Environment variables are not hard-coded in the codebase, reducing the risk of accidental exposure through version control systems or code reviews.
  • Environment variables are stored outside of the codebase, making it harder for attackers to access them directly from the application's source code.
  • Environment variables can be managed securely on the server, allowing for easy rotation and revocation of keys without changing the code.

3. Code snippet to prevent Zoom API JWT Key hardcoding using HashiCorp Vault

Using HashiCorp Vault for managing Zoom API JWT Keys is a great way to enhance security. Here are code snippets in five different programming languages for securely handling a Zoom API JWT Key using HashiCorp Vault.

Remember to replace the VAULT_ADDR and VAULT_TOKEN with your Vault server address and authentication token. The snippets assume that the Zoom API JWT Key is stored under the api_key field within Vault. The specifics of the Vault path and field names should be adjusted to match your Vault setup.

How to generate a Zoom API JWT Key?

To generate a Zoom API JWT Key, follow these steps:

  1. Log in to the Zoom Developer Console.
  2. Click on the "App" tab and select "Develop" from the dropdown menu.
  3. Click on the "JWT" tab and then on the "Create" button to generate a new JWT Key.
  4. Copy the generated JWT Key and use it in your API requests to authenticate with the Zoom API.

My Zoom API JWT Key leaked, what are the possible reasons?

There are several reasons why a Zoom API JWT Key might have been leaked:

  • Improper storage: If the JWT Key is stored in plain text in a code repository or configuration file that is accessible to unauthorized users, it can be easily leaked.
  • Weak access controls: If the system that generates or uses the JWT Key does not have proper access controls in place, unauthorized users may be able to access and leak the key.
  • Phishing attacks: Developers or team members may fall victim to phishing attacks, resulting in the unauthorized disclosure of the JWT Key.
  • Malicious insiders: An insider with malicious intent may intentionally leak the JWT Key for personal gain or to harm the organization.
  • Unintentional sharing: Developers may accidentally share the JWT Key in communication channels or public forums, leading to its leakage.

What are the risks of leaking a Zoom API JWT Key

When it comes to the Zoom API JWT Key, it is crucial for developers to understand the risks associated with leaking this sensitive information. Here are some key points to consider:

  • The Zoom API JWT Key is used for authenticating requests to the Zoom API on behalf of an application. If this key is leaked, unauthorized parties may be able to access and manipulate sensitive data within the Zoom platform.
  • Leaking the Zoom API JWT Key can lead to potential security breaches, data leaks, and unauthorized access to Zoom accounts and meetings.
  • Developers should never hardcode the Zoom API JWT Key directly into their code or expose it in public repositories. Instead, they should securely store the key using a reliable secret management solution.
  • Regularly monitoring and rotating the Zoom API JWT Key is essential to minimize the risk of unauthorized access and potential security incidents.

Zoom API JWT Key security best practices

  • Avoid embedding the secret directly in your code. Instead, use environment variables or secrets managers
  • Secure storage: store the Zoom API JWT Key in a secure location, such as a password manager or a secrets management service.
  • Regular rotation: periodically rotate the API key to minimize the risk of long-term exposure.
  • Restrict permissions: apply the principle of least privilege by only granting the key the minimum necessary permissions.
  • Monitor usage: regularly check the usage logs for any unusual activity or unauthorized access attempts.
  • Implement access controls: limit the number of users who have access to the secret and enforce strong authentication measures.
  • Use a secrets manager: utilize secret management tools like CyberArk or AWS Secrets Manager for enhanced security.

By adhering to the best practices, you can significantly reduce the risk associated with Zoom API JWT Key usage and improve the overall security of your Zoom API JWT Key implementations.

How to check if Zoom API JWT Key was used by malicious actors

  • Review Access Logs: Check the access logs of your Zoom API JWT Key account for any unauthorized access or unusual activity. Pay particular attention to access from unfamiliar IP addresses (if you haven’t set up a specific allow list) or at odd hours.
  • Monitor Usage Patterns: Look for anomalies in the usage patterns, such as unexpected spikes in data access or transfer.
  • Check Active Connections and Operations: Review the list of active connections and recent operations on your database. Unusual or unauthorized operations might indicate malicious use.
  • Audit API Usage: If possible, audit the usage of your API key through any logging or monitoring services you have integrated with Zoom API JWT Key. This can give insights into any unauthorized use of your key.

Steps to revoke the Zoom API JWT Key

Generate a new Zoom API JWT Key:

  • Log into your Zoom API JWT Key account.
  • Navigate to the API section and generate a new API key.

Update Services with the new key:

  • Replace the compromised key with the new key in all your services that use this API key.
  • Ensure all your applications and services are updated with the new key before deactivating the old one.

Deactivate the old Zoom API JWT Key:

  • Once the new key is in place and everything is functioning correctly, deactivate the old API key.
  • This can typically be done from the same section where you generated the new key.

Monitor after key rotation:

  • After deactivating the old key, monitor your systems closely to ensure that all services are running smoothly and that there are no unauthorized access attempts.

How to understand which services will stop working

  • Inventory of services: keep an inventory of all services and applications that utilize your Zoom API JWT Key.
  • Communication and documentation: Ensure that your team is aware of which services are dependent on the key. Maintain documentation for quick reference.
  • Testing: before deactivating the old key, test your services with the new key in a staging environment. This helps in identifying any services that might face issues post rotation.
  • Fallback strategies: Have a fallback or emergency plan in case a critical service fails after the key rotation. This might include temporary measures or quick rollback procedures.

In summary, the remediation process involves identifying potential misuse, carefully rotating the key, and ensuring minimal disruption to services. Being proactive and having a well-documented process can greatly reduce the risks associated with a compromised API key.
